Sadly (for me) it appears that one of my batteries is losing the ability to take a charge. I may just go with one battery for now until I can figure out what I want to do.
SDS100/SDS200: Data only Mini USB cable?
- Thread starter garys
- Start date
Strike the above. Apparently when doing the battery swap, I put the discharged battery back in the radio. 
Did you check the red wire for voltage? Red isn't ALWAYS +power.
Maybe this would be a solution? https://a.co/d/7WRWnMQ
I use these to keep voltage out of my 3D printers from the raspberry Pi running octoprint.

Yeah, China cables have all sorts of colors in them and they don't bother to use them for their correct functions as no one are supposed to see the wires. I've cut some USB cables to use them for experiments and in half of the cases the wire colors are wrong according to standards of red for +5 volt and black for minus or ground.

I cut the red wire and then removed the battery. Then I tried to to power up the scanner without success. Unless you are positing that the red wire was ground and one of the other three wires was actually power I'm confident that this cable was built to the standard.
Thanks!
I'll order that today and see if it works. If not, I can always return it. I'll report back with the results.
As @ProScan pointed out in this thread the +5v power may be required to activate the UART chip.

I'm interested to see if that works or not and my theory holds up.
My theory is based on all the scanner models BCD996P2 and above. The scanner stops sending answer back polls after the computer reboots even when ProScan, Butel, Freescan are not running prior to the computer rebooting. The only way to resolve that is power cycling the scanner or reinserting the USB cable.
When someone else asked about a data only cable years ago I said it wouldn't work as I had tried and it needed the +5, another member shot me down and I just assumed he was correct and didn't pursue it any further.
I'll post the results. It's supposed to be here on Wednesday, but might show up earlier.
I think it's still not going to work...
It does make sense to power the UART from USB power...
Running the scanner from a USB wall wart, who cares if it's running...
But running on battery power only, should be a little less draw on the scanners battery... How much less, who knows...

When you have +5v on the USB it will power the whole scanner from that USB power, so no real reason to power the UART separetly from the scanners own voltage from a power perspective.
If the UART are powered by +5v then the USB signalling of 5v are of no issue. But if the UART are powered by the scanners +3.3v then it might be a different case, if it struggles to output more than 3.3v or have issues receiving +5v signalling. So logically the UART should be powered by +5v if the IC isn't specifically designed to be powered by 3.3v

The dongle arrived and it's a no go. Same as the modified Mini USB cable. Which I expected. I ran the same test with my 325P2 and got the same results. Again what I expected.
